[0025] The high-precision fine adjustment device for inclined assembly of a speed reducer of the utility model is composed of a balance beam 1, a hanger ring 2, a size adjustment plate 3, a gear nut 4, a pinion 5, a rotating rod 6 and a lengthened hand lever 7, and the specific implementation is as follows: Figure 1As shown, the use is as follows Figure 3 As shown.

[0026] Symmetrically arranged on the balance beam 1 are several adjusting screw holes 8 and a pair of lifting lugs 9.

[0027] The balance beam 1 is welded by steel plates and profiles, and after welding, ultrasonic flaw detection is qualified, and the specific implementation is as shown in Figure 4 As shown.

[0028] The fine adjustment function of the tilt assembly high-precision fine adjustment device of the reducer is that the small gear 5 (M2, Z15) rotates to drive the large gear nut 4 (outer teeth M2, Z100, inner thread M42* pitch 3) to rotate, thereby driving the lifting ring 2 to rise and fall. The small gear 5 rotates 24°, and the lifting ring 2 fine adjustment distance is 0.03mm, and the specific implementation is as shown in Figure 5 As shown. Among them: M represents the module, and Z represents the number of teeth. When the height needs to be adjusted, rotate the small gear 5, and then drive the large gear nut 4 to rotate; the rotation of the large gear nut 4 causes the relative torsion between the inner thread of the large gear nut 4 and the outer thread of the lifting ring 2, so that the lifting ring 2 realizes lifting.

[0029] In order to avoid high-altitude operation, a rotating lengthening hand lever 7 is adopted, and the assembly worker manually rotates to transmit the torque to the small gear 5 through the rotating rod 6, and the specific implementation is as shown in Figure 6 As shown.

[0030] The tilt assembly high-precision fine adjustment device of the reducer can hoist reducers of different sizes, which is realized by the size adjustment plate 3 in different adjusting screw holes 8 of the balance beam 1, and the specific implementation is as shown in Figure 7 As shown.
